The Antonine Ditch has been clearly detected by both survey techniques; the magnetic response is generally uniform across the site while the resistance anomalies vary, depending on localised natural factors. Evidence for the Rampart is more tentative and intermittent, though at their most coherent, the magnetic responses suggest a partially intact base constructed of highly magnetic cobbles. The Military Way remains elusive; though a few faint trends have been identified which might represent the line of the road, natural and modern agricultural factors make this interpretation highly inconclusive. The ditches of the fortlet appear in both datasets but no obvious internal features have been detected. No anomalies that can be obviously attributed to postulated Rampart towers have been identified; the nature of these features makes them very difficult to detect by either technique, thus an absence of geophysical evidence cannot prove or disprove their presence along the Antonine Wall.
